Bigger, more potent hits than other vape pens.The toxin levels decrease with lower temp,” said Strongin.Best Weed Pens Reviewed 1. “We have no evidence so far of finding toxins from terpenes at lower temps. “Such problems may be avoided by the use of vaporizers, which don’t attain the high temperatures of combustion that cause these chemical changes.”ĭabbing at lower temperatures will result in a vapor with significantly less carcinogens. “The essential problem here is combustion, which breaks down terpenes and other compounds into other, potentially toxic compounds,” he said. Gieringer is also keenly aware of the detrimental effects of dabbing at high temperatures. Using a torch to heat the nail so far appears to produce the most toxins from terpenes.” “Hotter temperatures afford more toxins,” he said. While some electronic dabbing rigs do exist, the more common method is to use a culinary torch to heat the nail, which results in inconsistent and imprecise temperatures when dabbing.Ĭontrolling temperature is “critical” to limiting exposure to carcinogens, said Strongin. Uncontrolled heating can result in the temperature of the nail being well above that recommended range. However, dabbing presents a problem in that there must be proper temperature control of the nail to vaporize the BHO and not burn it.Īppropriate vaporizing temperature can vary, depending on the makeup of the BHO and the user’s preference, but it’s typically around 572˚F to 662˚F (300˚C to 350˚C), according to the researchers. Vaporization occurs at lower temperatures than combustion, resulting in the formation of fewer toxic compounds when inhaled. “Therefore, one might reasonably posit that smoking poses greater hazards than dabbing,” he said.Īrguments for the safety of vaporizers and e-cigarettes often bring up vaporization versus combustion. Marijuana that’s smoked contains cellulose and other carbon compounds not found in marijuana concentrates. Gieringer notes that like with tobacco, there are differences in composition between marijuana smoke and vapor. Studies exist comparing the carcinogenic effects of cannabis and tobacco, but there have yet to be any that compare smoking and dabbing. “In short, some of the toxins in regular smoked marijuana may also be produced by dabbing,” he told Healthline. “It has long been known that the combustion of marijuana (or tobacco) produces benzene, acrolein, and scores of other noxious compounds,” said Dale Gieringer, PhD, director of the California National Organization for the Reformation of Marijuana Laws (NORML). While the discovery of the relationship between terpenes and carcinogens may be a new development, others say that finding benzene and other toxic substances in BHO should be expected. ![]() “When heated as part of a cannabis concentrate formulation via certain methods of dabbing, they can degrade to produce toxins.” “Terpenes are believed by many to be harmless flavorants because they are natural products,” Robert Strongin, a study author and professor of organic chemistry at Portland State, told Healthline. Terpenes are used in essential oils and cosmetics, and serve as flavoring additives for electronic cigarette and vaporizer products. They give marijuana plants their wide variety of aromas and fragrances. ![]() More specifically, scientists identified that terpenes, a class of organic compounds found in marijuana, are responsible for the resulting carcinogens when smoked or vaporized. New research from Portland State University has now identified that dabbing vapor contains known carcinogenic substances, including methacrolein and benzene. On account of this, scientific data on BHO consumption is limited. This form of consumption is new, only becoming popular in the past few years. It’s also viewed by some as being easier on the lungs than smoking marijuana. Marijuana concentrates are often extracted using butane, resulting in a final product called butane hash oil (BHO).īHO goes by a variety of names, typically based on its consistency: wax, oil, shatter, and butter (or budder).Īccording to recent survey data, users seek out BHO for a “cleaner,” more concentrated high. The user applies the marijuana concentrate, or dab, to the nail, releasing vapors that they inhale. However, unlike a traditional pipe, dabbing rigs use a small heated surface, called a nail, typically made of glass, metal, or ceramic. The latest trend in marijuana consumption, researchers now say, produces carcinogenic substances.ĭabbing uses highly potent marijuana concentrates that are vaporized on a special dabbing rig, similar to a glass water pipe.
